Abstract:

Distributed Virtual Reality （DVR） has the distinct interactive characteristics of virtual reality and the distribution characteristics of network, so it meets the needs of the collaborative work for long-distance users Due to the constraints such as network bandwidth, delay and heterogeneity, DVR sy stem demands that 3D graphic files should be as small as possible and have the characteristics of cross-platform. This paper introduces the principles, methods and realization process of interactive techniques between users and virtual scenes based on X3D, and provides a typical application example.

Key words: （distributed virtual reality;dynamic interactive;X3D;Java）
